Answer:
x^2 + 11 x + 28
Step-by-step explanation:
Expand the following:
(x + 4) (x + 7)
(x + 4) (x + 7) = (x) (x) + (x) (7) + (4) (x) + (4) (7):
x x + 7 x + 4 x + 4 7
x x = x^2:
x^2 + 7 x + 4 x + 4 7
4×7 = 28:
x^2 + 7 x + 4 x + 28
7 x + 4 x = 11 x:
Answer: x^2 + 11 x + 28

Answer:
plane containing a line
Step-by-step explanation:
In accordance with a plane postulate corollary, it is concluded that, for a given PLANE CONTAINING A LINE, there is one and only one perpendicular line through a given point on the line.
Hence, in this case, the correct complete statement is written as: Given PLANE CONTAINING A LINE there is one, and only one, a line perpendicular to the plane through that point.
Two buckets of seawater contain kg of salt.
Step-by-step explanation:
Amount of salt in 1 kg water =
It is given that;
1 liter =
500 liters =
500 liters = 548 kilogram
As,
1 kg of seawater = of salt
548 kilograms =
548 kilograms = kilograms of salt
Two buckets of seawater contain kg of salt.

Answer:
There is evidence that the nutrition label does not provide an accurate measure of calories in the bags of potato chips at 5% level of significance.
Step-by-step explanation:
Given that the nutrition label on a bag of potato chips says that a one ounce (28 gram) serving of potato chips has 130 calories and contains ten grams of fat, with three grams of saturated fat.
Sample size of 35 gave mean as 134 with s = sample std dev = 17
(two tailed test)
Mean difference =
Std error of sample mean =
Since only sample std deviation is known, we use t test
df =34
t = mean diff/std error = 1.392
=0.1729
Let us fix significance level as 5%
since p <0.05 we reject null hypothesis
There is evidence that the nutrition label does not provide an accurate measure of calories in the bags of potato chips
